DUAL-TIRE WHEEL FOR AUTOTRUCKS.

Application filed. January 6, 1912.

Specification of Letters Patent.

Patented July 16, 1912.

Serial No. 669,753.

To all whom it may concern:

Be it known that I, PHINEAS Jones, a citizen of the United States,residing at Oak street, Metuchen, county of Middlesex, and State of NewJersey, have invented certain new and useful Improvements in Dual- TireWheels for Autotrucks, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.

This invention relates to an improvement in the wooden bodies or spokesand follies of wheels for auto trucks which, when required to carryheavy loads, are provided with dual-tires.

It is now the useage adopted by the automobile association to make thetelly of a single-tire wheel three-quarters of an inch less in widththan the nominal width of a single tire, but in making a dual-wheel theadopted usage is to make the telly twice the width of the tire, thusrequiring the dual wheel fellies to be one and a half inches wider thantwo of the fellies for a single wheel. Heret-ofore, the wide fellies tosupport dual-tires have often been provided with a single set of spokesat the middle of their width with the fellies overhanging veryconsiderably at both sides of such spokes. The wood required to makefellies ten or twelve inches wide is difficult to obtain and alsoexpensive, whereas the wood required for making tellies four and aquarter or five inches wide can be purchased and worked much morecheaply.

In the present invent-ion, I form the dualtire wheel of two similarsingle-tire wheels having their hubs mounted upon a sleeve withintermediate spacing flanges, and secured rigidly thereon, and thefellies of the two wheels secured together by throughbolts. I thus avoidthe use of wide timber in making the fellies of the dual-tire wheel. Inmaking a wheel with rim ten inches broad to receive two tires tour and aquarter inches wide each, I thus employ two single wheels each having aset of spokes with fellies and bands four and a quarter inches wideeach, and bolted firmly together with intermediate blocks or thimblesone and a half inches thick.

The drawing illustrates a wheel with ten inch rim, Figure'l being anelevation of the wheel; Fig. 2 is a plan of the same; Fig. 3 is asect-ion of the same, and Fig. 4: a plan of the hub with interlockedflanges between the two sets of spokes; Fig. 5 shows the hub with aspool bet-ween the sets of spokes. Fig. 3 is drawn upon a larger scalethan the other figures.

The ten inch rim upon the wheel is made of two fellies a, a, each fourand a quarter inches wide, and intermediate packingblocks Z) one and ahalf inches wide. Bolts Z2 are extended through the tellies and theblocks, clamping the whole rigidly together. The metal bands 0, c, whichare shrunk upon the fellies, are also four and a quarter inches wide,and the rubber-tires or threads (Z, d are fitted to such. bands. It isimmaterial how the tires are attached to the bands. Two sets of woodenspokes c, c carry wooden fellies a, a, and are clamped with intermediateflanges upon a sleeve 9 which is made of suitable bore to fit an axleand turn thereon or be driven thereby, as may be required.

It will be noticed in Fig. 3 that the spokes are not dished butperpendicular to the axis of the wheel and shaped (see Fig. 1) to form asolid mass of wood between the clamping flanges, so as to be bored witha cylindrical hole. Such spokes necessarily require spacing-flanges fbetween them, the same as spacing-blocks are required between thefollies a, a.

One of the flanges or collars g is made integral with the sleeve, andone set of spokes is clamped against the flange g by a flange f andbolts 7b. The other set of spokes is clamped between inner and outerflanges f, f by bolts h, and through-bolts h embrace all of the flangesto clamp all of the parts rigidly to the integral flange g. The flangesf form the spacing element of the hub, and are connected together byteeth 6, as shown in Fig. i, or by forming them integral with the bodyof a spool, as shown in Fig. 5. Where the teeth c' are employed, thethrough-bolts it serve to hold them in rigid engagement.

In the construction of automobiles various parts are made by difl erentmanufacturers, and it is common for the maker of the automobile tofurnish the sleeve for the truck-wheels and obtain from a wheelmakcr thewooden portions of the wheel including the spokes, tellies and bandsshrunk thereon. My invention thus permits the automobile-maker to employa straight sleeve with a bore to fit the shaft or journal of theautomobile and with a flange to which the wooden parts of the wheel canbe securely bolted, and to employ mere duplicates of the parts employedin constructing single-tire wheels. The construction greatly facilitatesthe manufacture of dual-tire wheels, as it enables the stock forsingletire wheels to be used, without change, in fitting up dual-tirewheels.

Fig. 3 shows the very small amount that the fellies overhang the spokeswith my construction, in which two sets of spokes are used, each setstanding directly under the middle of one of the tires.

The drawing shows that the fellies, the spokes, and the angle-collars fare the same as are used in constructing a single-tire wheel, and thatonly the flanges f connected together would difier in the dual-tireconstruction. The dual-tire wheel is thus made of two similarwheel-bodies, with their hubs interlocked and mounted upon the samesleeve, and their rims secured rigidly to gether by through-bolts.

The fellies are shown in Fig. 1 with the usual joints a between thesections of each telly.

Having thus set forth the nature of the invention what is claimed hereinis:

1. A dual-tire wheel comprising two wooden fellies with interposedspacingblocks and connected by clamping-bolts,two sets of spokes fittedperpendicularly within the two fellies and tapered at their inner endsto form a solid mass of wood bored the same for both sets,spacing-flanges fitted between the sets of spokes at their bore, flangesfitted outside of the spokes, and bolts extended through the fourflanges to clamp them together.

2. A dual-tire wheel comprising two wooden fellies with interposedspacingblocks and'connected by clamping-bolts, two sets of spokes fittedperpendicularly within the two fellies and tapered at their inner endsto form a solid mass or" wbod bored the same for both sets, flanges atopposite sides of each set of spokes with bolts h to clamp.
